- The MCR and ESGR Air Conditioning System upgrade project includes the installation of two additional chillers it is necessary to remove each train of chilled water from' service for seven days to complete the installation of the chilled water connections for the additional chillers. The modifications will require planned entries into Action.
Statement 3.23.C.2 with Dng inoperable AHU in the MCR and Dag inoperable AHU in the ESGR of each unit to complete. These modified action statement will only be used for the installation of the chilled water connections in the MRC and ESGR Air Conditioning System and will expire June 30,1992.

Basis When the supply of compressed bottled air is depleted, the main control room and emergency switchgear room emergency ventilation system is manually started to continue to maintain the control room pressure at the design positive pressure so that leakage is outleakage.
One train of the main control room emergency ventilation consists of one fan powered from an independent emergency power source.
The main control and emergency switchgear room emergency ventilation system is designed to filter the intake air to the control room pressure envelope, which consists of the control room, relay rooms, and emergency switchgear rooms during a LOCA.
High efficiency particulate air (HEPA) filters are installed before the charcoal adsorbers to prevent clogging of the iodine adsorbers. The charcoal adsorbers are installed to reduce the potential intake of radio iodine to the control room. The in place test results should indicate a system leaktightness of less than 1 percent bypass leakage for the charcoal adsorbers and a HEPA effic!cncy of at l9ast 99.5 percent removal of DOP particulates. The laboratory carbon sample test results should indicate a radioactive methyl iodide removal efficiency of at least 95 percent for expected accident conditions. The control room dose calculations assume only 90 percent iodine removal efficiency for the air passing through the charcoal filters. Therefore, if the efficiencies of the HEPA filters and charcoal adsorbers are as specified, at the temperatures, flow rates and velocities within the design values of the system, the resulting doses will be less than the allowable levels stated in Criterion 19 of the General Design Criteria for Nuclear Power Plants, Appendix A lo 10 CFR Part 50.
If the system is found to be inoperable, there is no immediate threat to the control room, and reactor operation may continue for a limite<* period of time while repairs are being made. if the system cannot be rer sd within the specified time, procedures are initiated to establish conditions ror which the filter system is not required.

The Main Control Room (MCR) and Emergency Switchgear Room (ESGR) Air l Conditioning System cools the control room, the control room annex and the Units j 1 and 2 emergency switchgear rooms. The air conditioning system includes three,
chillers (1 VS E 4A,4B, and 4C) and eight air handling units (1 VS AC-1,2,6,7 and 2 VS.AC 6, 7,8, an') 9).
Inte; m modifications were completed on the MCR and ESGR Air Conditioning Systeto to address interim failure and increased cooling requirements for the E3 Gas. Permanent modifications willinclude replacement of the MCR and ESGR AHlls and installation of additional chiller capacity to restore original design fleb lity.
Units 1 and 2 MCR and ESGR AHUs have been replaced in the initial phases of the permanent modification, restoring redundancy to the AHU portion of the origina.I system design. As a result, the following MCR and ESGR equipment is required tc operate to maintain design temperature under maximum heat load conditions:
Two chillers One Unit 1 MCR AHU and one Unit 1 ESGR AHU
+
One Unit 2 MCR AHU and one Unit 2 ESGR AHU
+
in addition to the equipment restrictions above, a fire watch will be required during this interim period in both unit's ESGR and MER #3 to address Appendix R considerations.
